Title: Ink jet recording head
Inventor: NAKAYAMA KAZUYA
IPC: B41J2/055
Filed: 1994-10-27
Abstract: PURPOSE: To absorb the vibration of a recording head and to enhance quietness at the time of recording by bonding a metal plate to the surface to which a piezoelectric element deformed by the application of pulse voltage to reduce the vol. of an ink pressure chamber of the recording head is fixed through a viscoelastic self-adhesive. CONSTITUTION: An ink jet recording head 1 is constituted so that a piezoelectric element 1a (14a) receives DC voltage to generate tray-shaped strain by counter piezoelectric effect to pressurize ink and the outflow of the ink in an iris direction is reduced by the fluid resistance of an iris 12 to emit the ink from a nozzle 13a. In this case, a metal plate 2 is bonded to the surface to which the piezoelectric element 1a is fixed of the recording head 1 through a viscoelastic self-adhesive 3. By this constitution, the deformation determined by the rigidity of the recording head 1 and the metal plate 2 is generated by the vibration of the recording head 1 caused by the strain of the piezoelectric element 1a but kinetic energy is converted to heat energy when the viscoelastic self-adhesive 3 is deformed to reduce vibration to reduce noise.
